SPECIFICATION forming part of Letters Patent No. 276,248, dated April24, 1883. Application filed July 8, 188:2. (No model.)

To all whom it may concern: I

Be it'known that I, ISAIAH SMITH HYATT, of Morristown, in the county ofMorris and State of New Jersey, have invented a new and usefulImprovement in the Manufacture of (301- lars, Oufi's, &c., fromCelluloid, of which the following is a specification, reference beinghad to the accompanying drawings.

The invention has relation to improvements in the manufactureof collars,cufls, and analogous articles from the material known as celluloid andother compounds of pyroxyline.

Difficulty has heretofore been experienced in producing from pyroxylinematerial collars,

cuffs, and analogous articles of perfectly sat-- isfactory whiteness. Toobviate this difficulty is the object of the invention, which isaccomplished by using a backing or a filling of a blue tint instead ofwhite, as has hereto: fore been customary.

In Figure 1 of the accompanying drawings a cuff is shown ill section asillustrating the use of the back or filling as I employ it. In Fig. 2,which is an end view, A denotes the filling, inclosed between two layersof white material, B (J.

In practice I take sheets of celluloid or other pyroxyline material, asthey are customarily made when intended to be used in the manufacture ofcuffs, collars, and similar articles, and secure them to the back orfilling in any convenient and appropriate way, forming the article asmay be desired. The only difference between my method and that now invogue is that instead of usihg a white backing or filling I use one ofablue shade or tint. I have found that a light shade of blue is to bedesired, although I do not limit myself to any particular shade of blueor to any particular method of securing it in place.

I hereby disclaim the invention described ill the patent granted to P.D. Aub, February 17, 1874.

WhatI claim as my invention, and desire to secure by Letters Patent, is

A collar, cuff, or similar article made of celluloid or other compoundof pyroxyline ill which a backing or a filling of a blue shadeor tint isemployed, substantially ill the manner and for the purpose set forth.

In testimony that 1 claim the foregoing improvement in the manufactureof collars, cuffs, &c., from celluloid, as above described, I havehereunto set my hand this 13thday of May, 1882.

ISAIAH SMITH HYATT.
